Arkansas Highway 140

Highway 140 (AR 140, Ark. 140, and Hwy. 140) is a designation for two east–west state highways in the Upper Arkansas Delta. One route of about 32.70 mi begins at Highway 14 in Marked Tree and runs east to US 61 in Osceola. A second segment of 1.93 mi in east Osceola runs from US 61 to Pearl Street and Quinn Avenue. Both routes are maintained by the Arkansas State Highway and Transportation Department (AHTD).

History
Present-day Highway 140 was created on April 1, 1926 as State Road 40, one of the original Arkansas state highways. On November 25, 1958, the route was renumbered to Highway 140 after the American Association of State Highway Officials (AASHTO) designated Interstate 40 in Arkansas.

The original Highway 140 was created between March 1930 and June 1931 from US 65 in Dumas westward to Garrett Bridge. This route became part of AR 54 in 1937.
